Title: Improvements in valves or obturating devices for fluid pipes and containers under high pressure, particularly fire extinguishers and the like
IPC: F16K35/02
Filed: 1940-04-24
Abstract: 624,404. Manually-actuated valves. REMUS, V. April 24, 1940, No. 7396. Convention date, April 29, 1939. [Class 135] A valve for fire extinguishers &c. comprises a body screwed into a highpressure container or pipe-line 2, Fig. 1, and having an outlet 3, the flow through which is controlled by a valve 4 having a white-metal &c. sealing ring 6 co-acting with a seat 5 upon which it may be jammed after normal closure. The valve is opened against the pressure in the container by a lever 16 through an aperture 17 in which passes the end 10 of a member 8 having a valve disc 11 with a white-metal sealing ring adapted to coact with a seat 13 and to which the valve 4 is connected. The lever is positioned on the end 10 by clamping-nuts 18, 20 having spherical seating faces adapted to be engaged with like faces on the lever. To open the valve 4 and close the valve disc 11 and thus prevent leakage past the valve actuating means, the lever 16 is depressed. Closure of the valve 4 and opening of the valve disc 11 is effected by raising the lever, jamming of the valve 4 on its seat being achieved by screwing -the nut 20 down on to the lever. Fig. 6 shows a modification in which the valve 4 and the valve disc 11 can be jammed on their seats by springing the end of the lever 16 into notches 29, 30, respectively, in a locking lever 27. Fig. 8 shows another arrangement in which a second spring-loaded valve 37 is provided. In a further modification, the end 10, Fig. 9, is connected to the member 8 by a ball-joint, and the valve disc is provided with alternate packing-rings 8b and 8c of lead and hard metal respectively. The Specification as open to inspection under Sect. 91, comprises also a modification in which the lever 16 bears directly on the top of the stem 8 to jam the disc 11 on its seat, while a spherical-faced nut on the stem coacts with the body to jam the valve 4 on its seat. In another arrangement, in which the washer 20 is dispensed with, a second lever adapted to be engaged with the underside of the washer 18, effects jamming of the valve 4. In other forms, the jamming of the valve 4 is effected by a spring. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in cigarette packing machines
IPC: B65B19/04
Filed: 1959-03-04
Abstract: 886,499. Hoppers. ARENCO A.B. March 4, 1959 [March 14, 1958; May 23, 1958], No. 7593/59. Class 78 (1). [Also in Group XVII] A cigarette-packaging machine comprises a cigarette hopper, the volume of which is automatically varied to absorb excess supply or demand. In one embodiment, one side of the hopper is formed by a belt 6 (Figs. 1, 2) which is slackened to increase hopper capacity. Cigarettes are supplied by a conveyer belt 1 to the hopper from which they fall into the usual channels 25 for discharge by a plunger in batches to pockets 4 in a wheel 3 forming part of the packaging- apparatus. The belt 6 is wound on a drum on a shaft 9, the latter being connected by worm gearing 16-19, 21 to a shaft 22. Free on the shaft 22 are sprockets 38, 39 having clutch elements 24, 26 for engagement by a member 27 movable under the influence of solenoids 32, 33. The clutch member 24 is coupled to the conveyer shaft 15 and driven with it by a motor 46, and the member 26 is coupled to the packaging wheel drive-shaft 48 rotated by a motor 53. The shaft 9 drives through gearing a switch arm 14. Operation.-If, for example, the supply conveyer 1 should stop, a switch 57 on the shaft 15 breaks the circuit to the solenoid 32. As both solenoids are in circuit during normal running, the solenoid 33 will cause clutch members 26, 27 to be engaged so that shaft 9 is driven anticlockwise, as shown in Fig. 1, from the package wheel drive-shaft 48. The belt 6 thus tightens and feeds cigarettes to the channels. Eventually, if the supply conveyer is not restarted, the arm 14 operates a switch 59 to stop the machine. If the packaging wheel should stop, a switch 58 on the shaft 48 de-energizes the solenoid 33, whereby the shaft 9 is driven clockwise by the shaft 15 and the belt 6 slackens to absorb the input. Eventually, if the packaging is not recommenced, the switch arm operates a switch 69 to stop the machine. In normal operation, if the hopper is initially empty the supply conveyer starts when the machine is switched on and automatically drives the shaft 9 to slacken the belt until at about half hopper capacity the switch arm 14 operates a switch 63 (Fig. 2) causing the packaging to commence and restoring the clutch member 27 to the neutral position shown. If the hopper is full, the packaging wheel starts first and cuts in the conveyer at half capacity. In another embodiment, duplicate sectorshaped hoppers 118 supply a packaging wheel 77 and receive cigarettes from conveyers 76a, 76b. The hopper bases are formed by plates 80a, 80b pivoted at 81a, 81b and rising or falling to decrease or increase hopper capacity. Arms 99a, 99b move with the plates to operate switches 101a-104a, 101b-104b in connection with clutch means for driving the plates from the conveyers or packaging means in similar manner to that in the first embodiment. If one supply conveyer should fail, means are further provided for running the packaging wheel at half speed.

Title: Improvements in and relating to hydraulic motors
Inventor: CLARK RICHARD A
IPC: F03C1/40
Filed: 1964-02-25
Abstract: 1,048,591. Hydraulic reciprocating motors. AMERICAN BRAKE SHOE CO. Feb. 25, 1964, No. 7828/64. Heading F1A. In an hydraulic motor, e.g. supplied by an accumulator and coupled to a jet engine through an over-running clutch for starting, a by-pass passage 28, 29 between the motor inlet 20 and outlet 22 is controlled by a spring-loaded valve spool 26 subjected to the pressure differential across a restriction 24 in the motor outlet, such that valve 26 is opened to prevent overspeeding of the motor when the load is uncoupled from the motor. Valve biasing spring 30 is adjustable by a screw 31. The end faces of spool 26 are connected through passages 32, 33 to upstream and downstream of restriction 24. When the pressure differential across restriction 24 rises to a predetermined value, spool 26 is moved against spring 30 to open the by-pass passage via valve groove 26G, e.g. when the jet engine has started and the over-running clutch uncouples the motor.

Title: Improvements in or relating to radio-navigation systems
IPC: G01S1/02
Filed: 1946-03-13
Abstract: 629,947. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. March 13, 1946, No. 7838. Convention date, Oct.. 2, 1944. [Class 40 (vii)] A radio-navigation-system comprises a beacon defining a straight course-line on which are situated two transmitters transmitting respective trains of pulses having the same repetition rate and bearing a fixed phase-relationship with respect to one another, means being provided at a receiver on a mobile craft following the course-line for receiving the two trains of pulses and for deriving therefrom an indication of the position of the craft on the course-line when it is situated between the two transmitters. A pulse transmitter 1 radiates a train of pulses 2 and also actuates the transmission, from a responder beacon 3, of a train of pulses 4. A delay network is arranged within the beacon 3 and is so adjusted that the pulse train 4 when returned to the beacon 1 is 180 degrees out of phase with the train 2. The pulse signal received at a receiver 5 on an aircraft to the right (as shown) of the beacon 1 consequently contains no component at the fundamental pulse frequency, the modulation of the signal received being effectively of double the frequency transmitted. As the aircraft passes the beacon 1, however, the amplitude of the fundamental component increases while that of the second harmonic decreases so that the difference between their amplitudes becomes a measure of the range from the beacon 3. The receiver 5 accordingly applies the demodulated pulse signal to two frequency selectors, tuned to the fundamental and second harmonic respectively, the output therefrom being rectified and applied differentially to a meter which is calibrated in terms of range. The course-line C is determined by a localized beacon L. A further beacon G may be used to determine a glide-path for the aircraft. The pulse signal received in the aircraft may alternatively be applied to a cathode-ray tube and the range determined by a direct comparison of the pulse spacing. Specification 590,460 is referred to.
